Ideal Electrical 36-311 TKO 4-Piece Carbide Hole Cutter Kit with Smooth Start Pilot Bit & Carry Case - Perfect for Electricians, DIY Projects, and Metal/Plastic Drilling

Don't hesitate, buy this hole cutter set. I used this to cut multiple holes in Hammond Enclosure # EJ863 Junction Box and the tools worked awesome! The drilled hole sizes were accurate and the holes had hardly any burrs. The spring popped-out the center slug every time and the pilot drill...basically a center drill...started with ease. Using a center drill style pilot drill makes starting the hole much easier because of the small drill point...thin drill web...but the larger body diameter on the center drill reduces the chance for breakage. Great product, and if I need other sizes I will be going back to this brand first.
